}Questions
Which countries does it cover?
Every EU member state and Northern Ireland (prefix XI) through VIES. Greece is EL; a number sent with GR is checked as EL.
What if VIES or a member state is busy?
The check is retried for busy signals. If no clear answer comes, the call fails and is not charged; it never answers not valid by default.
Does every country return the name and address?
No. Each member state decides; Germany and Spain return valid or not valid only.
How do I pay?
Each successful call costs the tool's price; failed calls are not charged. The first 3 calls are free. Then pay with card credits from $1 (the key goes in an Authorization header or as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
